Wherein, for ease of description, anti-puncturing chip is split as multiple successively splicing anti-stab unit member 1 (practical being one
Body machine-shaping), anti-stab unit member 1 is positive trigone wimble structure, and each side of positive trigone wimble structure is respectively by one piece three
Angular protective plate 2 is constituted, and the waist of three pieces of protective plates 2 is successively spliced into and surrounds the trigone wimble structure, and trigone wimble structure is real
By three pieces of 2 integrated moldings of protective plate on border, protective plate 2 is titanium alloy substrate.
Further, for each anti-stab unit member 1, by the lateral surface of trigone wimble structure, i.e. three pieces of protective plates 2
Lateral surface formed structure be set as outboard structure 3, by the medial surface of trigone wimble structure, i.e., the medial surface shape of three pieces protective plates 2
At structure be set as inside structure 4.By successively splicing multiple outboard structures 3, while multiple inside structures 4 successively being spliced
To form entire anti-puncturing chip structure.

The deformation energy of piece, under certain cutter attack energy, titanium alloy chip when the side tilt angle of trigone wimble structure is 22.5 °
Plastic deformation ability is relatively large, larger to the kinetic energy loss of cutter, and puncture resistant ability is stronger.If the whole side length of anti-puncturing chip,
Height is certain, and in a certain range, triangular pyramid side length is bigger on chip, then anti-stab performance is lower, and side length is smaller, then anti-stab performance
It is higher, but the surface density of substrate is bigger.
By Experimental comparison, show that the bottom surface side length of triangular pyramid is 11.5mm, and when side tilt angle is 22.5 °,
Vertical height of the vertex far from bottom edge is 2.4mm.It is anti-stab in order to allow that the size of entire anti-stab unit member 1, which is scheduled on this specification,
The total number of layer unit component 1 can satisfy anti-shearing ability under appropriate circumstances.Wherein, if antipricking layer chip

Deng influence, the anti-shear performance of titanium alloy anti-puncturing chip can decline, and weak region is easier to be pierced through by cutter relatively.If three
Pyramidal structure quantitative design is excessive, then the area of monolithic titanium alloy anti-puncturing chip will reduce, although improving the anti-of antipricking layer
Thorn ability, but can greatly increase the weight of antipricking layer, it is unable to satisfy the requirement for mitigating quality.
Wherein, when the bottom surface side length of triangular pyramid is scheduled on 11.5mm, the influence of dimensional effect is effectively prevented, according to
" the police stab-resistance body armor of GA 68-2008 " tests the test of anti-stab performance, the big plate that the triangular pyramid unit of side length 11.5mm is combined into
Weight and cutter free-falling that row falling weight impact test is 2.4kg with total weight under the height of 1m is pounded and hits titanium alloy sheet,
By test of many times, titanium alloy sheet is never pierced, to prove that the titanium that the triangular pyramid unit of bottom surface side length 11.5mm is combined into closes
Golden big plate is able to bear the puncture energy of 24J, meets national standard.The thickness of protective plate 2 is ultimately determined to by test
1mm, thickness is bigger than normal, and anti-stab performance is no doubt excellent, but will increase the weight of titanium alloy sheet；Thickness is small, is unable to satisfy antipricking layer
Anti-stab performance.It is comprehensively compared, is most the side length of titanium alloy-based plate unit, thickness and the so positioned specification of bevel angle
Good design result.
